Deployment model of wireless sensors networks in the framework of hybrid sensors and vehicular networks for road safety

Abstract

Hybrid Sensors and Vehicular Networks (HSVN) represent an architecture which creates a framework of collaboration between Wireless Sensors Networks (WSN) and Vehicular Ad Hoc Networks (VANET). The goal of this collaboration is the improvement of the road safety. The coverage and connectivity problems (deployment models) of wireless sensors networks represent a big challenges studied by many searchers. The environment and application requirements have a relationship with the aspects used to create a deployment model. In this paper, we have proposed a deployment model of WSN used in HSVN basing on the roads network and application of road safety. This model uses an algorithm which has for purpose ensuring the sensing of any road event and allows the connectivity between sensors. The results proven that our proposition is more reliable than others works.
